Tests marginal response invariance at both levels on each dimension

four-by-four confusion matrix |
If the p value for either level of the x dimension is significant, we are justified in rejecting the null hypothesis of perceptual separability on the x dimension. Similarly for the y dimension.
The estimator is derived in a footnote of Thomas (2001).
